Downgrading admininstrator, upgrading user

I am the new administrator of a miniBB forum. My predecessor's user account (with user_id=1) has to be downgraded to a regular user, and my own user account (which is currently a regular user) upgraded to administrator. Although creating an entirely new user account to be the administrator is also a possibility.

How can I best do this?

I bet it's not as simple as just change the value of $admin_usr and $admin_pwd in setup_options.php into my own username/pwd, since from what I read the administrator must have user_id=1.

It can be changed directly in database by running an SQL query plus checking some settings; it's a custom job and I recommend you to use Paul's custom support: Premium miniBB Customers Support to have it done quickly and professionally.

Then in the users table, you just need to assign a non-existing user ID to the earlier admin's account, preferrably it should be the next ID in the auto-incremental order following the current max. ID. Otherwise, you must assign userID=1 to your current regular account. The SQL commands may look like these:

update minibbtable_users set user_id=... where user_id=1;update minibbtable_users set user_id=1 where user_id=...;

Also change setup_options.php assigning the same admin's password as for your current regular account.

Done it.I created an entirely new user account with a non-personal name to become the administrator. Then switched both user_id's directly in the database like you said and voila. Maybe in the future I will change all the rest (posts, PM's etc), but at the moment I can live with seeing old postings of the previous admin with the undertitle still saying 'Admin'.I will use the admin account only for admin purposes. For the regular chatting etc. I keep using my regular account.Thanks for your help.
